Schritte zur Lösung

∣ 1 - 3 c ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

1 - 3 c = - 20 or 1 - 3 c = 20

1 - 3 c = - 20 or 1 - 3 c = 20

c = - \frac{19}{3} or c = 7

14 ∣ x + 14 ∣ + 13 = 69

∣ m ∣ = 14

\frac{x}{2} - 1 = 1

∣ 5 + 2 j ∣ = 9

\frac{x}{4} - 2 - 3 = 0
